I'm sorry BB..
My cat (Angel) is 15 (I didn't think that was *very* old) - She's very healthy, empathetic, sentient guardian spirit cat. She has bad anxiety (About me leaving - She *knows* when I'm going to leave/Cuz I'd be packing my bags - She is, for after all, my *trip cat*).
She goes under my covers and cuddles with me every night before I go to bed (Sometimes she falls asleep), and then (When I want to sleep), she climbs on my desk chair, and sleeps there all night (Until I wake up). I cried.. I know she's getting old.. Because it's so so sad.
She is my childhood cat. Two of my moms friends will visit every day to give her and Conan (My moms black cat) food, water, clean the litter box. I left toys, a laser etc all over the floor. They might hang out there and keep them company some days for 3 weeks.
